Specification of Letters Patent.

Patented I une 25, 1918..

Application led May 12, 19117. Serial N o. 168,191.

To all whom t may concern.'

Be it known that I, FERDINAND R. WOL- TER, a citizen of the United States, residing at Minneapolis, in the county ofHennepin and State of Minnesota, have invented certain new and useful Improvements in Mop- I-Iolders, of which the following is a Specifcation.

The present invention relates to mops and more particularly to mop holders or those devices used for securing a mop-rag or the like to a handle. The present invention is an improvement `0n applicants Patent No. 1,037,703.

The object ofthe present invention is to simplify the construction and operation and to produce a more effective means for securing or locking the mop-fabric to the holder, as well as to produce a neater device. It is also an object of the invention to provide such a device that may be cheaply constructed.

The features of the invention reside particularly in the construction and organization of parts which will be readily apparent from the following` description setting forth in detail the specific construction of applicants invention.

One of the important features of this invention is the provision of a substantial channel-shaped clamping bar having its ends bent at an angle and out of the plane of the body portion of the clamping bar, the juncture of the body portions with the end portions of the clamping bar being depressed or bulged so as to form a recess or depression in which is to engage the eX- tremity of hook members provided for securingA and clamping the bar into position. This peculiar construction prevents the hook members from accidental or casual disengagement from the clamping bar during the use `of the mop, thus insuring a constant securement of the clamping bar in clamping position during ordinary use of the mop.

In the accompanying drawings illustrating the invention:

Figure 1 is a top plan view with the mopholder constructed in accordance with the invention, p

Fig. 2 is a longitudinal sectional view taken through the mop-holder as shown in `lii 1 li'ig is a transverse section taken substantially on line 3-3 of Fig. 1, and

e an enlarged fragmentary def tailed view illustrating the peculiar formation of the ends of the clamping bar and.

and arranged to provide a tubular extension 1 adapted to be secured to one end of a mop handle 2. `The members a and b are arranged to have their opposing edges spaced relative to each other to form the slots 3. A cross-head composed of the two plates 4 and 5, secured together by rivets or other fastening means 6, is disposed between and secured intermediate its ends to the outer ends of the members a and b by suitable fastening means 7, the members a and being flattened at their outer ends for facilitating the securement of the cross-head thereto. The plates 4 and 5 have their outerside edges flared relative to each other to provide receiving lips '8, with which cooperates a detachableclamping bar 9 which is preferably of a channel formation as shown. The mop-cloth is secured betweenlthe lips 8 by the clamping bar 9 which is moved into cooperative clamping engagement with` the lips by a yoke member 10 slidab-ly disposed? between the members a and b of the tubular extension 1. The arms of the yoke member diverge from the extension to extend in proximity to the cross bar and have their extremities formed with the inwardly extending hooked portions 11 engageable in the opposite `end of the channel of the clamping bar 9.

To effect the clamping of the clamping bar 9 a compression spring 12 is disposed between the members a and b and has one end bearing against the yoke member 10. The members a and b provide a housing for retaining the spring in position. There is also a link, slidably disposed between the members a and which has its ends extending through the slots 3. These ends are pivotally connected to the operating lever 14 intermediate its ends to form a loop member 13. The loop member has the end lying between the members a and b adapted to engage with and bear against the other end of the spring l2 in er' er to compress the latter upon an operation of a lever 14. This lever is, preferably, stamped from sheet .metal to conform t the curvature of the tubular extension .l so as to lie flat there- 5 against and thusavoid all= projections which might 'otherwise occur.

One end of the lever let; is engageable in teeth of a notched fin 15 secured on the outer surface off one of the members ,ai or b so that,

When it is desiredttoclamp a mop-fabric be tive'enthe clampingbar and thecross-head, Ithe end 16 of the lever may be adjusted to engage .in one of the. notches, which Will; act as a fulcrum, and then swung thereabout. Therefore, it will be manifest that When the lever is moved totheposition shown. in Figs.

, l and2., thespring engagingend ofthe .loopt 113 vvill compress fthe -lspring 1,2, which compression vvillbe exerted; upon the yoke mem- 20 ber? 10v (.seeFigt 2);for movingthe latten to,

draw the bar 9 into cooperative clamping relation Withy the cross-head of the mop.

Fig, 4 clearly shows the .manner in which the opposite ends. of theclamping bar 9. are formed to,provide an eflicient means forpreventingthe-armslt() of the yoke from spreadingland the-hooked extremities thereof from becomingdisengagedz from the bar through ordinary use. Eaclrend-lwof the bar 9 is bentat'an angle relative to the body portion of. the clamping` bar. and out of-y the f plane. thereof, asclearly illustra-ted. The point of; juncture betvveenthe ends..9LL and the body portion of; the bar isbulged or de-. pressed asindicated ati 9b toprovide-a recess in the ,channeledfsurfaceoff the bar,;in which recess theextremity l1*vl of the hooked ends 11 of the armsof the yoke 10 tightly and frictionjally engage. when the parts are in the, positions shown in Figs. 1, and 2.v By this vconstruction it Will be seenl that should l. anyferceorpressure .beapplied to the arms of. thefyoke. 10 `Which would tend tospread them the extremity lel.a will; engage the' inc linedsurface of the bent end 9a. of the, bar and thereby tightly; Wedge into engagement 1 Withthedoar,k in such amanneras,Wouldv prevent the.y disengagement ofI the ends n 11 of the yoke from the bar. This construction is an; improvement: over the construction shown in applicants priorpatent, men- ,v tioned above.

Thea-rms of the. yoke vl()-slidably extend through i the guides L7 providedv by separatingo-r,flaringv apart the ends of the` plates 4 and 5i0f the cross-head;` By thisarrangement ;the,yoke member isretained in a definite position relative tothecrossfheadand its movement isrestr-icted-'to asliding movementsrelativethereto. It also Willbel ob`- v-ious, by this -v arrangement, that the clampf ing loer-931s,movablefbyv theyoke into clamping engagement with; the.' stationary cross- .halqanl-is.detachable so as tofaeilitate the removal 4and renewal of the mop-fabric.

Suitable securing means, such as are shown by the bolts 1S, may be employed for fastening the members a and to the handle 2. As illustrated, one of the bolts passes through the notched lin l5 for securing the salne in position.

For purposes` of hanging the mop up when not in use, an opening 19 is provided through the members aand by through which a nail or other suitable projection may extend.

The above clearly describes the invention, however, it is to be understood that certain changes in the construction, combination and arrangement of'parts may be resorted to that fall Within the legitimate scope of the appended claims.
